GANG=PLOW.

SPECIFICATION forming part of Letters Patent No. 395,831, dated January8, 1889.

Application filed April 28, 1888. serial No. 272,173. (No model.)

To all whom it may concern.-

Be it, known that I, WILLIAM HOLLOWAY, of Gilroy, Santa Clara county,California, have invented an Improvement in Gan g-Plows and I herebydeclare the following to be a full, clear, and exact description of thesame.

My invention relates to the class of gangplows; and my inventionconsists in the novel land-gage wheel and the mechanism for operatingit, and also in the arrangement of the carrying-wheels, theircrank-axles and connections, whereby the plow is regulated as to depth,leveled, and turned to or from the land, all of which I shallhereinafter fully describe.

The object of my invention is to provide a gang-plow having an effectiveland-gage wheel, whereby I am enabled to dispense with the ordinarylandsides on the plow-bottoms, and, generally, to provide a simple andreadilyadjustable machine or implement.

Referring to the accompanying drawings for a more complete explanationof my invention, Figure 1 is aperspective view. Fig. 2 is a horizontalsection through the beams of the frame to show the bearing-plate F andaxle E. Fig. shows the manner of pivoting the bearing-plate to theframe.

A is the plow-frame, to the beams of which are properly secured thestandards I) of the plow-bottoms B, which are of ordinary construction,with the exception that nothing in the shape of a landside is used.

C is the forward axle, having a crank, c, on one end, the journal ofwhich carries the forward wheel, D, which is located in front of theplows and upon the furrow side.

E is the rear axle, which is journaled in a bearing -plate, F, held upunder the plowframe by means of a vertical pivot pin or bolt, f, onwhich said plate may have a slight movement to vary the angle of theaxle E to the frame. Upon the outer end of the axle E is pivoted acrank, c, the journal of which carries the rear wheel, G, which is thelandgage. Its location is opposite the plows and on the land side, beingarranged to travel on the land, and not in the furrow at all. A lever,H, is attached to or formed with the pivoted crank e, and said levercarries a spring-controlled pawl, 71, which is adapted to engage with arack-segment, h, which is pivoted on the end of-the axle E, beside thecrank e and lever H. Bolted to the side of the rack h is an arm, 7L2,from which a connecting-link, I, extends to a crank, c, on the end ofthe forward axle, O.

Extending upwardly from the crank c, which carries the forward wheel, isan arm, J, from which a link, j, (adj ustably connected with it by aseries of holes and a removable bolt in the ordinary manner) extends toand is adj ustably connected with a lever, K, pivoted to the frame A andhaving a pawl, 13-, which, un-

der the influence of a spring, 71:, is adapted tov engage a curved rack,15 whereby the lever is held in position.

At the back of the frame A is pivoted a lever, L, from the lower end ofwhich a connecting-link, Z, extends to and is connected with the pivotedplate F, which carries the rear axle, E, said plate being guided in itsmovement by a slotted or grooved bearing, f, at one end.

The operation of the plow is as follows: In order to regulate the depthof the plows or to raise them up, I operate the lever K, so that throughthe connecting-link and arm J the crank-axle C is turned, which, throughits connecting-link I on the other side, the segmentrack h, pawl 72, andlever I-I, turns the crank e 011 the rear axle, E, and thus the wholeframe is raised or lowered on both wheels. To level the frame, which isnecessary, by reason of the front wheel traveling in the furrow and therear wheel on the land, the lever H is operated by releasing it from therack h, so that it may turn the freely-pivoted crank e without affectingthe other connections, and this operation takes place without stoppingthe horses. To turn the plow to or from the land and gage it properly,the lever L is operated, which, through the link Z, turns the plate F onits pivot, and thus, through the rear axle, E, turns the wheel G eitherto or from the land or straight ahead, so that the plow is directedaccordingly.

I am aware that plows are known in which the landsides of theplow-bottoms are omitted and a wheel is substituted to serve as arolling landside; but these wheels are mounted at an angle to the groundand usually have angular or beveled peripheries, and they follow theplows in the furrow made just ahead.

My invention is not to be confounded with these devices, for my wheel Gis not of this class. It is simply a gage-wheel to direct the plow to orfrom. the land. Its location directly opposite the plow-bottoms is oi advantage in enabling it to better control the direction of the implementand to steady it when gaged.

Having thus described my invention, what I elaim as new, and desire tosecure b v lmtters Patent, is-

l.. In a gang-plow, the frame, the plow-bottoms carried therebv, and aearryi ng-whcel on the front of the frame on the t'nrrow side ot' theplow-bottoms, in combination with the carrying and gage wheel G, mountedopposite to the plowdmttoms and on the land side thereof and arranged tobe turned to an angle on either side of the line oi travel,\\"h i*reI)ythe plow is turned to or from the land, substz'intially as described,

2. In a gang-plow, the frame having the flow-bottoms and the frontcarrying-wheel on the fnrrow side, in combination with the rear carryingand gage wheel on the land side, a pivotallyanounted axle carrying saidwheel, and a lever and connections with said axle, whereby thegageqvheel may be turned to or from the land, substantially asdescribed.

l. In a gang-plow, the frame having the plow-bottoms and the frontcarrying-wheel on the furrow side, in combination with the rear carryingand gage wheel on the land side, the axle carrying the wheel, thepivoted bearingplate carrying the axle, and the lever-and-l'nkconnection to the pivoted plate, whereby the gage-wheel maybe turned toor from theland, substantially as describe].

l. In a gangplow, the l ralnc having the 1,)low-b )ttoms, the frontcrank-axle and carrying wheel thereon, the rear axle having a pivotedcrank and the carrying-wheel on said crank, and the con neetion s,wherel)y the crankaxles are operated to raise or lower the plow and to levelit, consisting of the lever II, eonnect'cd with the pivoted crank of therear axle, the pawl of the lever and the independent pivoted rack withwhich the pawl engages, the lever K, arm J, and eonneeting-link to thefront axle, and. the crank o and connectinglinl: I to the pivoted rackof the rear axle, substantial ly as described.

5. In a gang-plow, the frame having the plow-bottoins, the frontcrank-axle and carry" ing-wheel on the furrow side, the rear axlepivotally 'nn'ninted and having a pivoted crank, and the carrying andgage wheel mounted on said crank and opposite theplowbottoms on the landside thereot,in combination TWltll the lever Ii and connections forturning the pivoted rear axle and directing the gage-wheel to or fromthe land, the lever l'I,eonnectcd with. the pivoted crank of the rearaxle to r levelii'lg the plow, and the lever K, and connections betweenit and the lront axle and between thelront axle and the crank ot' therear axle,whereby the plows are raised or lowered,substantially asdescribed.

In wit ness whereol I have hereunto set my hand.

WILLIAM HOLLOWAY.
